Fault
Possible cause
Troubleshooting
Residues on the utensils or in the
appliance - coloured and easy to remove
Yellow, orange, brown soapy residues
inside the appliance
Soapy film formed from food components
and limescale. In view of the tolerances
of multi-component detergents (3 in 1 or
more), using them may make it necessary
to use the water-softening system if the
water’s hardness rating is 16°dH or higher.
► Advise customer:
Contrary to the detergent manufacturer’s instructions, also activate the water-
softening system and use salt
Residues on the utensils or in the
appliance - extensible rails
or residues on the cutlery drawer
It is possible for detergent and food
residues to be deposited, depending on
the appliance design and how it is used
► Clean it by hand
?
Use a modified set of extensible rails for the upper basket
?
For the cutlery drawer use a repair set
Detergent substances are deposited.
These deposits cannot usually be removed
with chemicals (appliance cleaner).
► Advise customer:
Change to a different detergent. We recommend using separate products (branded
detergent, salt, rinse aid)
► Clean the appliance by hand with a cloth
The water-softening system has been set
to a marginal value; there is regularly a
“white coating on the floor of the tub”
► Establish the correct water hardness rating and check and adjust the softening
setting.
►
Changing customer settings - Set water hardness (Page 15)
Regeneration salt on the utensils:
- Salt dispenser cover not tight
- Regeneration valve not tight
► Advise customer:
Eliminate the leak
► Adjust the water-softening system.
► Check the regeneration valve and make sure it is properly seated (customer
service programme)
Detergent residues in the rinse cycle; de-
tergent transfer
► Check the operation of the detergent dispenser, the dispenser cover must not be
obstructed by utensils.
► Check the non-return valve.
Wrong programme selected (Quick Wash
programme was selected)
► Select a suitable programme (see IM, Programme overview)
Deposits - water-soluble, wipeable
in the tub or on the door
Glasses beginning to become cloudy -->
can only apparently be wiped off
-
See Damage to utensils -->
Clouding of glass
Detergent substances are deposited.
These coatings cannot usually be removed
with chemicals (appliance cleaner, ...).
► Advise customer:
Change to a different brand of detergent. We recommend using separate products
(branded detergent, salt, rinse aid )
► Clean the appliance by hand with a cloth
Hardness range incorrectly set or total wa-
ter hardness greater than 50°dH
► Checking the residual hardness in the washing and rinsing cycle
► Set up the water-softening system as described in the instruction manual, replenish
the salt (see IM, water-softening system)
Deposits - white, difficult to remove
(limescale)
Limescale on the utensils, the contain-
er or the door
Water-softening system is not being regen-
erated
► Use the customer service programme to test the operation of the regeneration
valve
